Spot on. A 1Gb mp4 would be great. I am noticing that a 1.5Gb file (avi or mp4) is becoming de facto in some places. I just watched a copy this size of "Ill Met By Moonlight," and it was nice.

It's really too bad that IA derivations now only split to ogv and 512kb mp's--only because they are nearly equal in quality and the resulting choice is thus not so great.

Also, when I have posted x264 mp4's, IA doesn't derive.

It's all a work in progress. I'll take mine with everything.

Actually, when I suggested '1MB MPEG4', 1MB was referred to the encoding bitrate, which would be double what IA uses now for MPEG4 derivatives. This would yield much better video quality from those huge MPEG2s, which are encoded at 4-8MB. I use a 1630-2160KB overall bitrate for my x264/aac MPEG4 uploads, and IA derives those Ok. I used to upload DivX/aac MPEG4s (much faster encoding), but after IA changed their encoder again about 6-10 months ago derivatives were made out of sync. *sigh* It is a work in progress, indeed.

Do you transcode with 2 passes? 1630--2160KBit/sec. seems quite high for H264.

Not since I switched to H-264.

Well, I think we're both talking, in somewhat different ways, about the same result. A better encoding rate (&) file size, no matter what the container or codec. I'll try another mp4 and see what happens, as it has been a year, roughly, since I have.

Yeah
